On my 260C, there are some chrome strips that run across the top of the door cards and they are sandwiched against the internal version of a weather strip kinda thing, a padded strip that sits against the window. The chrome trims are cracked and the padded strip bit is probably a bit tired too
Here is a photo taken from the end of the door card, removed from the car
